Proteins, colloquially also called proteins, are made up of amino acids. Proteins belong to the basic building blocks of all cells. They not only give the cell structure, but are the [[Molekül/en|molecular]] "machines" that transport substances, pump [[Ionen/en|ions]] into and out of cells, recognize chemical reactions [[Katalys/en|catalyse]] and [[Signalstoff/en|signal substance]]. The building blocks of proteins are certain amino acids known as proteinogenic, i.e. building proteins, which are linked to chains by peptide bonds. Humans are 21 different amino acids - the 20 long known and selenocysteine.
